Excited-State Energetics and Dynamics of Large Molecules, Complexes and Clusters.

Abstract

Seeded supersonic expansions constitute a 'new state of matter', where interrogation by laser and other spectroscopic methods open up new horizons in the exploration of energetics, dynamics and photochemistry. We have studied the excited-state energetics and dynamics of some large finite systems with a large number of vibrational degrees of freedom. These involve large collision-free molecules and van der Waals complexes and clusters. We have perpetuated a broad research program of spectroscopy in supersonic jets, with a special emphasis on excited-state energetics in the high-energy domain and ultrashort relaxation phenomena.
